Serenity/JS

Serenity/JS is a framework designed to make acceptance and regression testing of modern full-stack applications faster, more collaborative and easier to scale.

Visit serenity-js.org for the latest tutorials and API docs, and follow @SerenityJS and @JanMolak on Twitter for project updates.

Serenity/JS Mocha

@serenity-js/mocha contains an adapter you register with Mocha test runner to enable integration between Mocha and Serenity/JS.

Installation

Install Mocha version 8.x or newer:

npm install --save-dev mocha@8.x

Install the @serenity-js/mocha adapter, as well as @serenity-js/core and any Serenity/JS reporting modules you'd like to use, for example @serenity-js/console-reporter:

npm install --save-dev @serenity-js/{core,console-reporter,mocha}

Usage with standalone Mocha

To use Serenity/JS with standalone Mocha, for example to run tests of REST APIs, you'll need a setup file that configures Serenity/JS reporting services.

JavaScript

If you're writing your tests in JavaScript, create a setup.js file (for example under spec/support/setup.js, but you can use any location you like):

// spec/support/setup.js

const 
    { ConsoleReporter } = require('@serenity-js/console-reporter'),
    { configure } = require('@serenity-js/core');

configure({
    crew: [
        ConsoleReporter.forDarkTerminals(),
    ],
});

Next, run Mocha as follows:

mocha --reporter=@serenity-js/mocha \
      --require=spec/support/setup.js \
      'spec/**/*.spec.js'

TypeScript

If you're writing your tests in TypeScript, you might want to run them via ts-node, which transpiles TypeScript in memory without you having to do it before every test run.

npm install --save-dev typescript ts-node

If you haven't done so already, configure your TypeScript transpiler via tsconfig.json:

{
  "compilerOptions": {
    "target": "es2018",
    "lib": ["es2018"],
    "module": "commonjs"
  }
}

Create a setup.ts file (for example under spec/support/setup.ts, but you can use any location you like):

// spec/support/setup.ts

import { ConsoleReporter } from '@serenity-js/console-reporter';
import { configure } from '@serenity-js/core';

configure({
    crew: [
        ConsoleReporter.forDarkTerminals(),
    ],
});

Next, run Mocha as follows:

mocha --reporter=@serenity-js/mocha \
      --require=ts-node/register \
      --require=spec/support/setup.ts \
      'spec/**/*.spec.ts'

Using Mocha configuration file

Please note that you can use Mocha configuration file to simplify your command line execution.

For example:

# .mocharc.yml
reporter: '@serenity-js/mocha'
require:
  - ts-node/register
  - spec/support/setup.ts
check-leaks: false
timeout: 5000
v8-stack-trace-limit: 100
# ...other config

Usage with Protractor

Configure your Protractor installation as per instructions in @serenity-js/protractor module.

Next, instruct Serenity/JS to run your tests using Mocha. You can also use your protractor.conf.js file to configure Mocha if needed:

// protractor.conf.js

exports.config = {
    // Tell Protractor to use the Serenity/JS framework Protractor Adapter
    framework:      'custom',
    frameworkPath:  require.resolve('@serenity-js/protractor/adapter'),
  
    serenity: {
        runner: 'mocha',        // Use Mocha
        // ... other Serenity/JS-specific configuration
    },

    mochaOpts: {
        // Mocha-specific configuration
    },

    // ... other Protractor-specific configuration   
};
